• Aseptic technique should be used for all cannulation procedures.
  • Fistula should be mature, ready for cannulation with minimal risk for infiltration, and able to deliver the prescribed blood flow throughout the dialysis procedure.
  • Ensure needle cannulations of the ReTAP™ patch are evenly spaced along the length of the patch when used for vascular access and when repeated needle punctures may be necessary.
  • Mechanical damage to the patch may result from repeated needle cannulations, which could lead to hematoma or pseudoaneurysm formation.
  • Patients should be carefully monitored during and immediately following the dialysis procedure.
